I change the server - my blog is now loacated on a new server. I start at this new server with the new V 6.4.3 and my old DB from my V 5.2.2 with an update of it.

At this server - it is located in germany too - the time will be the UTC which is shown in the backend (System > Status) for the server. So I put under System > Regional > Time my local time in it to correct this.

All new posts now have the correct time, the comments to. But the analytics use the server time, I guess, not my local time, because in Monday evening at 22:30 I will get data for Tuesday at 0:30 (see screenshot). That is not correct I guess and a bug.

Hello,
In my settings server time is set +2 UTC, along to b2evolutiong time. But also in this case in analytics the time stamp shows UTC time. It is not really a problem but it reduces convenience also in bugtracking when comparing to server logfiles.
Is there a way to show server time in analytics?

I'm afraid that the almost all (not 100% sure, but 99.9%) the date calculation of b2evolution is made taking as reference the timezone defined for your PHP installation. In detail, the hits dates are saved this way, so the hist of your site are saved into the database in UTC +2.
